Backlinks are still on third position in the algorithms. Unique and quality content is really the basics. However, in the casino, etc. crowded market, content is not enough.
Why someone say that articles and guest posts do not work?
Of course, do not post article about roulette at screw drivers manufacturer blog, or similar schemes. Do not post your article in general article directories, where article about weight losing and yours about casino, are close placed, this will not help.
Try to post articles at the niche sites and blogs, very close to your niche. 
Try to get some backlinks from niche authority relevant directory (very relevant to the topic of your site/blog). Avoid spammy submissions to the junk general directories, with links to every imaginable sites and topics.
